Freezing rain is a self-limiting process due to latent heat release.  A cold northerly fetch at the sfc can usually make up for it, but in this case very heavy qpf can actually work against you.  (as opposed to the more typical / oppose scenario where you have warm right at the sfc and cold above where you need the heavy qpf)

GFS surface depiction is amiss in that scenario with a cold northerly drain with attendant ageo feed down from Canada. We know GFS surface temps up here are often too warm, unless  he and all of Maine are torched at the surface prior to LP deepening on the Cape that sounding is too warm at the lower levels. .

Model bias is a whole different can of worms.  Just trying to explain how it could theoretically be possible ;)

18Z GFS phases earlier and far enough offshore to wrap in the cold air sooner. A changeover with a couple inches in interior NCT and higher amounts as you move north and east from northern ORH into Central and Northern New England. Just one run but something to watch.  

This is exactly the scenario I think is plausible..and much more likely than the clipper. I thought we'd see each run look better on this over the next few days. Lets see what everything does

Unfortunately for James, mother nature doesn't give a phuck. Stowe deserved more snow than rain last January too.

And you deserved an eastern Mass only blizzard in Feb 2012...but yes, there are lots of times when deviations from climate norms make us think it should be the other way around.

Deserved is always an odd phrase though for weather which is so totally chaotic.
